what is hysteresis losses
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Give a brief idea of principle of hysteresis motor,application.
Hysteresis and eddy current loss constitute core loss. It can be reduced by replacing solid core by laminated core... by adeeb
Hysteresis losses depend on the type of metal used to manufacture the magnetic circuit of a machine. Most magnetic circuits are made from silicon steel. Generally speaking, there's not much you can do to reduce hysteresis losses as that has already been factored in by the machine's designer.
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
Because that's the very definition of hysteresis. The reason there is hysteresis is because some energy is required to change the magnetization of many materials - you can compare this to a type of friction, though the details vary from the usual friction.
to reduce the eddy current loss in the machine
A comparator will trigger at a set point as deigned Without hysteresis if the level is there for a very long time it will have the effect of oscillating back and forth . hysteresis is feedback to insure a dead band whereby it has to be one state or the other
Magnetic hysteresis is the phenomenon where the magnetization of a material depends not only on the current magnetic field, but also its history. When the magnetic field is applied and then removed, the material retains some magnetization, showing a lag or "memory" in its response to changing magnetic fields. This results in the characteristic hysteresis loop observed in magnetic materials.
what is hysteresis losses
It is a special type of synchronous motor.It works on the principle of hysteresis and the torque is produced due to hysteresis
can Hysteresis motor use like alternator
Hysteresis is a phenomenon where a system's output lags behind changes in its input due to the system's internal characteristics. Dead zone refers to a region in the input space where no output response occurs, even though the input may be above a certain threshold. Both hysteresis and dead zone can affect the accuracy and stability of control systems.
max hysteresis = max(O_decreasing - O_increasing) / (O_max - O_min)
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
